TOMSK, Dec 8 – RIA Tomsk. Scientists
of Tomsk State University (TSU) developed camouflage material which merges with
environment not only in visible, but also in an infrared range that, for
example, will allow soldiers to become imperceptible for infrared scanners, the
press service of the higher education institution reported on Tuesday.
"The group of scientists of the
Siberian physics and technology institute developed the material allowing
object to merge with the environment in the infrared spectral range as much as
possible. The masking effect is provided at the expense of special structure of
the camouflage which reflective ability is arranged under any background",
– it is told in the message.
It is specified that camouflage
materials usually "hide" object in visible part of a range of
electromagnetic radiation. And it is necessary to approach radiation from
object to the background radiation of the environment to hide it in an infrared
range – for example, from means of thermovision. TSU scientists managed to
reach it at the expense of special structure of material.

According to the press service, the
inside layer of the camouflage is made of the heat-insulating material Pyrogel
XT and reduces thermal radiation. The material of the intermediate layer has
cooling properties. The external layer from PFCA (Petryanov's filter cellulose
acetate) with inclusion of nanoparticles maintaining temperature to + 150
degrees provides the minimum difference of radiation thanks to what the object
becomes "invisible".
"Thus, the objects allocating
heat can be protected from the systems of detection using natural or artificial
illumination. <…> The development can be used, for example, at production
of overalls for hunters or soldiers. The research group took out the patent for
the invention", – it was added in the higher education institution.
It is noted that the prime cost of
the new product promises to be rather low. "The most part of the
components for this camouflage is available on free sale. The only expensive
and labor-intensive component in it is material PFCA with the introduced
nanoparticles which production requires a special equipment", – it is
explained in the message.
